The principal objects of the invention are, to enable the rapid construction of tire proof buildings, particularly of the small type used for dwellings or store houses. and to devise a structure which will be easy to TlZlllbl-L. and will produce a very strong and rigid structure.

The principal feature of the invention consists in the novel construction of boards of concrete shaped to overlap and having a longitudinal tongue projection on the inner side adapted to interlock with notched supporting members. and whereby the bottom edges of the roof structures are formed with integral gutters.

In the drawin s, Figure l is a perspective section of a portion of a building constructed in accordance with this invention.

Figure 2 is an enlarged detail of one of the boards.

Figure 3 is an enlarged detail of a modilicd structure of board with a longitudinal sloping gutter strip.

Figure l is a perspective detail in part section showing a modified means of fasten ing the boards in place.

In the building of small houses, storage sheds and all such like structures it has been common to construct them of wood which are not only subject to the danger of fire but as they are usuall constructed from rather green lumber, trey are practically uninhabitable very shortly after they are built and they are required to be covered.

The present invention contemplates a structure where there will be no shrinkage to take care of. The structure will be weather proof and will be very easily. assembled. It consists of in erecting a suitable frame work and providing on the frame work posts or studs 1 and rafters 2 for the roof structure, provided with external notches 3 which are preferably out with adownward slope.

Boards 4 are constructed of concrete preferably having a wire mesh reinforcement 5 therein and on the inward side they are formed with a longitudinal rib 6 which is sloped downwardly at an angle corre sponding to the angle of the notches 3 in the posts and rafters.

The upper edges of the board are preferably formed with an offset 7 on the outer side and the lower edges are formed with an offset 8 on the inner side, thus providing n (Li 1924. Serial No. 727,292.

an overlap for the boards when assembled in the structure w rich will provide an citiciently weather tight joint so that water will not leak through the joint.

In the constr ction of boards for the roofs of buildings, special boards are formed for the lower edges, as illustrated in Fig ure 1 in which the bottom edge is shaped to form a gutter 9 to receive and carry off the rain falling on the roof.

An important feature in connection with this bottom structure is that diagonally arranged ribs 10 raised from the outer surface are provided to prevent snow sliding and to direct the water fall on the main portion of the roof toward the end of the building.

A suitable cap structure 11 may be formed of concrete or other suitable material to close the meeting joint of the ridge of the roof.

In the detail illustrated in Figure 3 a tongue and groove bevelled joint is illustrated as a modification from the structure illustrated in Figures 1 and 2.

In Figure 4 a slight modification for vertical work for the sides of a building is shown where short lengths of iron are bedded in the concrete structure. These strips project from the inner sides of the board and may be nailed to the vertical supports. The boards will of course be made in various lengths and building structures can be standardized to use the standard lengths Without any necessity of cutting.

To erect a building of such material will be very simple, it being merely necessary to build the frame placing the notched vertical and 'rafter members at the outer sides and then simply laying the concrete boards in place.

The angle rigs on the back interlock with the supports and 'each'board placed in position over the other secures it firmly in position.

The fastening strips illustrated in Figure a ma be used as an auxiliary means for securing the boards in place if so desired.

What I claim as my invention is:

1. A building structure, comprising a plurality of structural frames spaced apart and each having a plurality of spaced notches in their outward sides, boards formed of concrete extending horizontally between and bridging said frames, and longitudinal ribs rr-r GIEJORGE STEVENSON, OF TORGNTO, ONTARIO, CANADA.

arranged on the inner side of said concrete boards adapted to enter said notches to secure the boards to said spaced frame.

2. A building structurea comprising a phi-- 5 rality of structural frames spaced apart and i each having a plurality of notches formed in their outer sides, and arranged at an acute angle to said outward sides, and boards of concrete extending longitudinally and bridging the space between said frames, each having acute angularly disposed ribs extending longitudinally of the inner faces thereof adapted to interlock with said notches.
